FRITZ I1. ANDREN, OF CHICAGO, ILLINOIS.

WIRE-COILING- MACHINE.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed November 19, 1914. Serial No. 872,927.

To all whom it may concern 'Be it known that I, Fnrrz L. ANDREN, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wire-Coiling Machines, of which the following is a specific ation.

My invention relates to machines which may be used for the winding of wires into cables or cable-strands. The object thereof is to lay a multiplicity of wires in helical form with sufiicient tension to hold them in proper relative position, to thereafter smooth them about a central mandrel or core and compress the resulting product into a substantial Structure, in which the wires are held in positive relation to each other.

The principles of my invention are illustrated in the drawing, in which Figure 1 is a side elevation of my improved machine; p

Fig. 2 is a vertical longitudinal section thereof;

Fig. 3 is a view of a part thereof taken on the line 3'3 of Fig. 1;

Fig. 4 is a similar view taken on the line 44 of Fig. 1; and I Fig. 5 is an enlarged view of a screw threaded mandrel.

Further describing my invention with reference to the drawings: 1 is a base upon which the several mechanisms comprising my machine may be assembled and mounted. 2 is'an upright secured to said base, upon which the principal winding mechanism is mounted. '3 is a head on said upright, having a longitudinal opening in which is journaled the hollow shaft 4? Said shaft is provided at one end with the pulley 5, and

on the other endis mounted the winding head and the devices for carr i g spools of wire which is to be manufactured into the finished roduct. Another hollow shaft 5' is journa ed within shaft 4, and is provided with a longitudinal opening or bore 6. On one end of shaft 5 is the pulley 7, while the other end is provided with a suitable squared opening to take the shank 8 of the mandrel shown in Fig. 5.

The winding mechanism carried on shaft 4 comprises arms 9, on which are mounted spools 10 of wire, the said spools being provided in number equal to the number of strands which are to be made into the cable. A hub 12 constitutes a winding drumland is Said smoothing devices should be provided vwith means for adjustment in any suitable manner which readily occurs to the skilled mechanic.

A shaft 20 mounted on the brackets 21, 22 and 23 extends longitudinally of the base 1, and at one end thereof adjacent to the uprlght 2 is provided with driving pulleys 25 and 27. The pulley 25 is connected to pulley 5 by a belt 28, and pulley 27 is connected to the driven pulley 7 by a belt 7 which is crossed as shown, so as to cause the shaft 5' to be rotated in the opposite direction to the shaft 4, which is actuated by ulley 5. It will be seen therefore that w en this portion of the apparatus is put into operation by the movement of the shaft 20,

the shaft 4, carrying the spools of wire and the wmdmgdrum or head, will be rotated in one direction, while the shaft 5, carrying the mandrel, will be rotated in the other di-' rection. The holes in the winding drum through which the wires 30 pass from the spools and are fed onto the mandrel or support should be arranged spirally about the said drum. The wires will then be wrapped around the mandrel or support even-1y,

smoothly and close together, while the mandrel revolving in the opposite direction and having screw corrugations tends to feedthe wrapped coil outwardly, and its progress" is aided by the winding spool 52 and compression rolls 36 and 40, which will later be described. The smoothing devices 19 on the face of the winding drum bear strongly upon the wires wrapped about the mandrel or about the central core, and smooth and level the said wires thereupon, thereby establishing a smooth and uniform outer face for the product. An attachment having the backwardly inclined arm 5 is mounted on the end of shaft 5' and acts as a guide to correct any irregularities in the wrapping of. the wires on the mandrel.

On the base 1 is mounted the pair of up- -which has the grooved face 40'.

held in elastic relation to each other.

rights 35. Transversely thereof is journaled a wheel 36, having in its face the groove 37. A pair of blocks 38 are slidably mounted in the said uprights and wlthin them is journaled the shaft 39 of wheel 40, A. bridge piece 41 is provided above said last-named wheel and an adjusting screw 42 is threaded therein and bears upon )a spring 43, whose ends rest upon the journal blocks 38, whereby the said grooved wheels may 12; shaft 36 is extended outwardly from the grooved wheel 36 and by means of the beveled gears 44 and 44: the shaft i5 and the beveled gears 46 and 46' receive power from the shaft 20. I

Beyond the mechanism last described is a winding apparatus by which the completed cable is wound upon a suitable spool. Said apparatus consists of the uprights 50, at the upper portion of which is journaled a shaft 51, carrying a removable winding spool 52. Theshaft 51 has a pulley 53, which is driven by means of belt 54 from the pulley 55 mounted on shaft 20. The end of the cable after it leaves the smoothing devices is carried through the grooved compression rolls 36 and 40 and is attached to the winding spool 52. Said spool and said grooved compression rolls should be so timed with reference to the coiling a paratus as to take up the cable accurately as coiled. The compression rolls it will be noted have a positive connection with the source of power, and are thereby adapted to aid the finished cable in passing from the mandrel, and, in fact, to regulate the speed with which it is taken therefrom. The said rolls have a further function, viz., of compressing the cable to a desired uniform external diameter, and'to this endthe'grooves 37 and 40 are given the proper form and dimensions therefor.

The take-up or receiving mechanism, in: cluding the spool 52, are belt driven, thereby givlng slight opportunity for variations of speed relative to the other portion of the apparatus. Such variation may also be provided forby anysuitable clutch or frictional mechanism which. will readily occur to the skilled mechanic.

The smoothing rolls 19, mounted on the face plate. 17 of the winding head, revolve with.

the head and are adapted to uniformly close the wires upon the mandrel and to press the different wires into their, proper and appropriate position with reference to each other making a smooth and uniform structure, which then passes on to the compression rolls by which it is finally sized.

I have thus far represented and described my invention and its operation with reference to a mandral mounted on the shaft 5, upon which mandrel the wires are wound.

As previously s'tated, shaft 5' is provided with a longitudinal bore 6. If it is de' sired to provide the finished cable with a central core, a wire indicated by the dotted lines 55 and fed from a drum 56 may be passed through said bore and extended in place of the mandrel through the center of the face plate 17 The same being extended between the compression wheels and attached to the winding mechanism the operation of the machine will be as before described, the wires being wound upon said wire as a central core which remains permanently in the cable instead of being wound upon the mandrel. And the smoothing and compression devices will act to complete the cable or strand in the same .manner as before described.

Having thus fully described my invention, what I claim as new and desire. to secure by Letters Patent is i 1. In a wire coiling machine; a' framework, a'coiling head revolubly mounted on the framework, a spirally corrugated man drel axially mounted within the coiling head, winding devices arranged spirally about said mandrel, and means for rotating the winding devices and mandrel relatively to each other. a
